The TPS3820-50QDBVRQ1 has a typical reset delay time of 200 ms. It operates over a wide supply voltage range from 1 V to 6.5 V, making it versatile for various applications. It features low supply current, enhancing power efficiency. The device is qualified for automotive applications, following the AEC-Q100 standard. It comes in a small SOT-23 package, which is space-efficient for compact designs. These features make it suitable for use in automotive, industrial, and other environments where reliable voltage monitoring and reset functionality are essential.

The TPS3820-50QDBVRQ1 is a voltage supervisor IC that comes in a 5-pin SOT-23 package. Its primary function is to monitor voltage levels in a system and provide a reset signal to the microcontroller or processor when the monitored voltage falls below a predetermined threshold. This ensures that the system operates within safe voltage levels, preventing malfunction or data corruption.
Key pins and their functions include:
- Pin 1 (GND): Ground reference.
- Pin 2 (MR): Manual Reset Input, used for triggering a reset manually.
- Pin 3 (OUT): Reset Output, which provides a reset signal to the processor.
- Pin 4 (VDD): Supply Voltage Input, where the monitored voltage is applied.
- Pin 5 (NC): No Connection, typically not used for any function.
The TPS3820-50QDBVRQ1 is specifically designed to monitor a 5V input voltage and will issue a reset if the voltage drops below approximately 4.65V.
